rental is for 'x' hrs
\n" ); document.write( "price is 'y'
\n" ); document.write( ".
\n" ); document.write( "y = 3.5(x-1) + 8
\n" ); document.write( ".
\n" ); document.write( "y = 3.5x -3.5 + 8
\n" ); document.write( ".
\n" ); document.write( "y = 3.5x + 4.5
\n" ); document.write( ".
\n" ); document.write( "He spent 18.50
\n" ); document.write( ".
\n" ); document.write( "18.50 = 3.5x + 4.5
\n" ); document.write( "3.5x = 18.50 -4.5
\n" ); document.write( "x = 14/3.5
\n" ); document.write( "x = 4
\n" ); document.write( ".
\n" ); document.write( "check using the facts
\n" ); document.write( "hr 1 = 8
\n" ); document.write( "hr 2, 3 & 4 = 3.50
\n" ); document.write( "3*3.50 = 10.5
\n" ); document.write( "8 + 10.5 = 18.5
\n" ); document.write( ".
\n" ); document.write( "Answer: He rented it for 4 hr.
\n" ); document.write( " \n" ); document.write( "
\n" );
